The "fundamentally flawed" revamp of Norwich's Anglia Square has sparked further criticism from heritage groups.
The Victorian Society and the Historic Buildings and Places group have added their voices to organisations which want plans for the shopping centre rejected, despite revisions by the developers.
Weston Homes and site owner Columbia Threadneedle revealed updated plans for the 1,100-home scheme on the shopping centre site last month.
The development includes 14 buildings ranging from one to eight storeys, along with new retail and commercial space.

The Norwich Society, Historic England and SAVE Britain's Heritage had previously objected to the revised proposals - alarmed at the height and massing of the buildings and their impact on the city's historic buildings.
The Victorian Society has now submitted its objection to Norwich City Council, with City Hall's planning committee due to make a decision on the scheme next month.
Connor McNeill, conservation advisor for the society, said the development would harm the conservation area and "negatively affect" buildings such as the 19th century, Grade II-listed Doughty's Hospital.
He said the society was also concerned at plans to demolish buildings in Pitt Street.
He said: "These early 20th century buildings have local significance and represent a rare survival in an area which has seen so much postwar development.
"Any acceptable proposal must consider more closely the historic character of the Conservation Area and the sensitivities of nearby heritage assets."
And Ross Anthony, from Historic Buildings and Places (also known as the Ancient Monuments Society), has submitted an objection from the charity.

He said it was a "fundamental flaw" that such tall buildings were planned.
He said: "No substantive changes have been made to the scale, design and massing of this development and the latest revision has again failed to address heritage concerns raised on numerous occasions."
Weston Homes is not commenting ahead of the planning committee meeting.
